I have a 2 year old male. I knew before I got him that iRNs are a little more difficult. He is loving, however he will suddenly bite very hard for no reason. He has bitten the upper lip of both my wife and my daughter. He also isn't a fan of his cage. We have a play pen perch that we keep him out on for most of the day the problem we are having (other than the biting) is he screams incessantly. He will scream about every 5-10 seconds for long lengths of time. His perch is in our living room, and he constantly flies down to try to get to us. That isn't really a bad thing, but my wife and daughter are shell shocked from him biting their faces. We are at our wits end with the screaming. We love him and don't want to see him go, but the only way we can quiet him is to put him in his cage in the other room. We don't want him to be sequestered in his cage all the time.
